What May cause responders and evacuees to become contaminated or need decontamination
Moving them down wind of the instant
333
When protecting people inside a structure close
All doors, windows, skiing, ventilation and air-conditioning systems
334
Evacuation may be better than sheltering in place when explosive vApors or gases are involved for two reasons

351
The basic principles of any decontaminated operation are
Get it off, keep it off contain it
352
Three types of Decon performed At hazmat incidents
Emergency , mass and technical
353
Offgassing occurs in
Fresh air And may require fans
354
I responders should avoid contact with products and or contaminated pools, puddles and or streams because
Fire fighter PPE can absorb flammable liquid which can later Ignite if exposed to an ignition source
355
Vapors from flammable and combustible liquids are usually heavier than
Air
356
flammable and combustible liquids are typically lighter than
Water and if so will float on the surface of water
357
Flammable and combustible liquids are class what materials
B . Water is an ineffective extinguishing agent
358
Leak control is often referred to as
Containment
359
Technician levels do not attempt offensive actions such as

360
Most cargo tanks have emergency shut off devices devices are usually located where
Behind the driver side cab
361
MC Dash 331 of 3500 Gallon capacity or larger should have two emergency shut off devices where
One on the tank behind the driver and the other on the rear of the tank on the passenger side
362
MC Dash 312/DOT Dash 412 do not typically have
Emergency shut off devices if they do it is located on the left front corner of the tank behind the driver compartment
363
Responders should not shut any valves without direction from
Facility or pipeline operators

The shut off is an in-line valve located on what side of the meter and how do you know it’s off
Owners side of the meter. To close the valve turn the tang till it’s 90° to the pipe
365
Spill control is not restricted to controlling liquids, responders may also need to confine dust, papers and gases with the following materials?

Permit service water runoff to pass Either under or over the damn while holding back the hazardous material
Under/overflow dam
373
If liquid is less dense than waterIt will

Foam concentrates are divided into two categories based on classifications of fuels which are
Class A Ordinary combustion
Class B for flammable and combustible liquids
381
Concentrates designs solely fir hydrocarbon Fires will not extinguish
Polar solvent alcohol (type of fuels/liquids that mix) fire regardless of the concentrations
382
Water miserable materials such as alcohols esters and keystones destroy regular fire fighting forms and require an alcohol resistant therefore ?
Firefighters should not use regular fluoroprotien and regular aqueous Film foaming foam on those materials
383
You may use Foam concentratesthat are intended for polar solvents on
Hydrocarbon fires
384
To produce high-quality form for elements are necessary

390
Most common cause of BLEVE is when
Flames contact the tank show above the liquid level in the tank show itself has overheated
391
When attacking fires of tanks apply continue water at what rate From white preferably
500 gallons/ minute,
Top of the tank with master stream
392
Oh natural gas is also shipped and stored as LNG He’s more likely to “” in this form
BLEVE in this form
393
I responders at a gas line leak should first
Evacuate the area immediately around the break and downwind
394
Materials that are loosely categorized as solids

Removal of ambulatory and non-ambulatory victims is called ?
Rescueing
398
Ambulatory Vs Non-ambulatory
Able to walk versus non-

414
illicit Biological agent manufacture falls under three categories BBV
Bacteria viruses biological Toxins
